Absolute rubbish!, connected a modest 13t motor powered it up, set the throttle range and the thing lasted about 30 seconds in a drift car on 2 cells.
Im an electronics tech so I thought I would disassemble and check over for dry joints ect as it didnt go up in smoke.. solder used on the PCB is terrible quality, bubbles when hit with precision iron.. heatsink is way too close to solder joints, I can imagine this is why some of them have gone up in smoke.. If i could rate it at no crowns I would..

I do not recommend this product, because for no reason it stopped working. Steering works, but not throttle. I can't even get it to arm, I have tried everything. When I tried another ESC the motor worked.

the price for this product is reasonable, also with fully powerful MOS-FET, it's totally working nice and I am recommending, the version 2 is new one now selling, that is inculding fan case with better quality, I bought a lot for my customer for beginner application.

My arrived, I made the proper connections, tested with the engine on the bench and it worked, did the beep normally. When I put it in the car it just vibrated the engine and did not work anymore. Measure the output with a true rms multimeter and this with a very low voltage, about 0.5 V. So does the beep, but too low for the hardly listen. I think it died before work.

i said that i would give more info once i managed to fix it. well, it's dead. it worked for 5 minutes on 2 cells lipo with an 6.5 turns motor that would draw a max of 60 amps. after this one i bought the 150 amps version. that one is still alive, but is not good. reverse is one big pulse, it gets hot, the original fan literaly exploded, etc. next time i think i'll go for a turnigy esc, since those usually do work the way they are intended to.

Recieved and never worked. No beeps when trying to program throttle. I spent hours trying different radio/receivers, different motors sensored and sensorless. I think I was shipped a dead one. Hobbyking should drop the Scanner Brand ESC's.

I got this ESC to use it with a Scanner 6T motor. The sensored part never worked and after less than ten minutes using it unsensored, the ESC smoke check. Since the motor works unsensored a 45amp Quick Series HK works great and is way cheaper. Scanner ESC has a poor quality for the price.
